Authenticate to multiple services and social networks

Is it possible, with the current web/oauth technologies, to create a web page, that, when visited by a user, would check all of his auto-login data (for example cookies to Twitter, Facebook and StackExchange), display the collected connection possibilities to him and say: "Hey, I can see you are using Twitter, Facebook and StackExchange. Do you want me to integrate with those, so that when you, for example, as a qu开发者_StackOverflowestion through my interface, it would get posted on all of those network?"
